GRAPHITAR® Grade CategoryChemical Compatibility of GRAPHITAR®
A B C D E F Resistance to chemical attack varies among GRAPHITAR® Grades. GRAPHITAR® Grades can be grouped into six chemical compatibility categories....see chart at left. A GRAPHITAR® component may be compatible with its chemical environment yet suffer mechanical damage from corroded mating parts. This situation can be avoided by specifying GRAPHITAR® for both mating surfaces
